S-Type Optical

Easy to adapt, ultra compact,
sub-Kelvin cryostat with optical window access.

S-Type Optical

The S-Type Optical is a very compact cryostat designed for a broad range of low-temperature experiments and applications that require simple and fast access to the sample stage. The system offers a unique combination of sub-Kelvin temperatures, automatic operation, and free-beam optical access on a small footprint.

Save money, time and valuable lab space.

One instrument to explore the full temperature range.

Various access options

Great endurance and fast regeneration

Single-shot performance of the S-Type Optical cryostat in S100g configuration with free-beam optical access, low resistivity DC wiring, and 4 RF lines installed. Starting at the bath temperature, the cryostat reaches the setpoint temperature within a few minutes. A target temperature of 1 K can be stabilized with ΔT/T<0.05% for more than 30 hours. The fully automatic regeneration process of the ADR takes less than 1.5 hours resulting in a duty cycle >95 %.
